Glass jars and containers are microwavable, dishwasher-safe, and freezable
Glass containers are a great alternative to plastic when it comes to freezing food. Glass jars and containers are microwavable, dishwasher-safe, and freezable. They are durable, easy to clean, and can be used multiple times, making them a more sustainable option than plastic. Glass containers are also safer for storing food as they do not leach harmful chemicals into the food, even when stored in the freezer.
However, it is important to note that glass can shatter when exposed to sudden temperature changes. Therefore, it is recommended to thaw frozen food in the refrigerator before reheating it in the microwave or oven. It is also important to avoid freezing liquids in glass containers as they can expand when frozen, causing the glass to break. When freezing food in glass jars, leave some space at the top to allow for expansion and prevent the glass from cracking.
Pyrex dishes and containers are a good option for freezer-to-oven meals as they are less likely to crack or shatter due to temperature changes. However, it is still important to avoid rapid temperature changes and not to tightly seal Pyrex containers, as this can create unwanted pressure and potential cracks.
Straight-sided mason jars are recommended for freezing food as they are easier to fill and clean than jars with shoulders. It is also important to use glass jars that are specifically meant for freezing and to avoid using glass jars from commercial products that may not be freeze-proof.
Overall, glass jars and containers are a safe and sustainable option for freezing, microwaving, and storing food without the use of plastic.

One of the key benefits of stainless steel containers is their ability to keep food fresh. They are designed with tight-fitting lids that create an airtight seal, preventing oxygen from reaching the food and slowing down the rotting process. This helps to extend the shelf life of your food, reducing waste and saving you money.
Stainless steel containers are also lightweight and portable, making them ideal for storing leftovers, meals, or snacks. They are safe to use in the freezer and oven, but it's important to note that they should never be used in the microwave. When it comes to storage, these containers are designed to nest compactly, taking up less space on your shelves.
Klean Food Solutions offers a range of stainless steel containers in various sizes and styles, including lunch boxes, bento boxes, and to-go containers. Their containers are leakproof, durable, and dishwasher-safe, making them a practical and eco-friendly alternative to plastic.
In addition to stainless steel, there are other options for freezing food without plastic. Glass containers, for example, are a popular choice as they are microwavable, dishwasher-safe, and often freezable. However, it's important to note that glass can shatter if subjected to rapid temperature changes, so proper defrosting is crucial.
Other alternatives include silicone freezer bags, beeswax wraps, and heavy-duty aluminium foil, each offering its own advantages in terms of sustainability and ease of use.
By choosing stainless steel containers and exploring other plastic-free options, you can effectively store food, preserve its freshness, and reduce your environmental impact.

Silicone is a sustainable alternative to plastic, being flexible, durable, and reusable
Freezing food without plastic is a great way to preserve flavour and nutrients while reducing waste. Some alternatives to plastic containers include glass, metal, and paper. Glass jars and containers are microwavable, dishwasher-safe, and often freezable, but it's important to avoid freezing liquids in glass as they can expand and crack when frozen. Metal containers are versatile and easy to clean, but they should never be used in the microwave. Paper options include heavy-duty, food-grade aluminium foil, which can be used to wrap most foods in the freezer, and beeswax wraps, which are waterproof, reusable, and compostable.
Silicone is a highly durable and versatile material that can be used as a sustainable alternative to plastic. Unlike plastic, which is made from petroleum, silicone is derived from silica found in sand and can withstand extreme fluctuations in temperature without melting, cracking, or degrading. This makes silicone products, such as straws, baking mats, and food storage bags, ideal for reuse, reducing the need for single-use plastics. Silicone is also odour and stain-resistant, hygienic, and hypoallergenic, making it suitable for food containers and lunchware.
While silicone is widely accepted as safe by organisations like Health Canada and the U.S. Food and Drug Administration, there is limited research on its long-term effects. Some studies suggest that silicone can leach synthetic chemicals, particularly into high-fat foods, and that siloxanes, the backbone chemical structure of silicones, can act as endocrine and fertility disruptors and may be potentially carcinogenic. However, in one study, no chemicals were detected in milk or formula after six hours of exposure to silicone nipples and bakeware. Additionally, silicone has a very low recyclability rate and is usually turned into industrial lubricant oil when disposed of.
Overall, while not a perfect zero-waste solution, silicone is a more sustainable alternative to plastic due to its flexibility, durability, and reusability. It helps reduce the reliance on single-use plastics and contributes less to the mounting plastic pollution in our environment.

Aluminium foil can be reused and preserves food in the freezer
Aluminium foil is not the most sustainable option for freezing food, as it ends up in landfills and the mining process creates greenhouse gas emissions. However, heavy-duty food-grade aluminium foil can be used to wrap most foods in the freezer as it protects against moisture, oxygen, and bacteria. Food experts recommend freezing food in foil for a maximum of a year, and it should not be used for highly acidic foods like lemons and limes as this can result in degradation and spoilage.
Aluminium foil can be reused, which makes it a more environmentally friendly option. To reuse aluminium foil, wash it in the dishwasher or with warm water and soap, and then flatten it with a rolling pin. However, foil that has come into contact with raw meat should never be reused. Here are some ways you can reuse aluminium foil:
- Use it as a static eraser by tossing a small ball of reused foil into your clothes dryer to reduce static cling without chemicals.
- Place a sheet of foil under your ironing board cover to improve ironing efficiency by ironing both sides of your clothes at once.
- Protect young plants from worms and other pests by wrapping a strip of foil around the base stem to prevent critters from crawling up.
- Stuff balls of used foil into the toes of shoes and boots to help maintain their shape when stored.
Other alternatives to plastic for freezing food include glass containers, stainless steel containers, and silicone bags. Glass containers are microwavable, dishwasher-safe, and often freezable. However, avoid freezing liquids in glass containers as they can expand when frozen and cause the glass to shatter. Stainless steel containers are versatile, easy to clean, and keep food fresh while locking in nutrients, but they should never be used in the microwave. Silicone is a more reusable and sustainable alternative to plastic as it is flexible, durable, and free from petroleum-based chemicals.
